Market does not seem to provide any valid solution to the new issues posed by a data economy which is characterised by a combination of increasing returns and legal blockers to community or ecosystem based competition. As a consequence, the current known optimal organisation to monetise big data and A.I. is the private or state monopoly. We review in this article possible alternatives that could be considered in the future and how to enforce them.

Nexedi does not use LXC containers or docker because it is impossible to ensure their stable operation especially in case of kernel ABI mismatch or missing containerisation of system calls. Instead, we use SlapOS nano-containers which have provided since 2010 similar benefits in a more stable way while using less resources. SlapOS nano-containers will soon be deployed on embedded device using Elbe embedded Linux with over-the-air (OTA) upgrade and secure boot.

Cloud Computing is essentially the automation of IT service provisioning through software which replace human tasks. It is currently evolving in multiple directions. Free Software and Open Hardware will eventually lead to massive price cuts compared to current price levels in USA or Asia. Edge Computing will reduce the need of data centres whenever network latency or availability become critical. Service Workers will eliminate the need of servers, both at the edge or at the data centre, in 90% cases. Big Servers will eventually replace smaller servers as the standard fabric the data centre.

OfficeJS Iodide notebooks can be used offline or online on any modern HTML5 web browser such as Firefox or Chrome. With the support of data science libraries such as NumPy, Pandas, Matplotlib, Plotly, etc. and soon scikit-learn, its nice to be server independent and carry on with data science just using browser. Hence, we tried to migrate some already famous lectures on data science on github. This web page mentions the steps and problems faced while migrating and obviously, the final result.

Rapid.Space is a new provider of low cost, ethical yet high performance servers targeted at big data applications, high performance computing, software development and large database applications. Rapid.Space provisions on each server a single "dedicated virtual machine" which takes control of all resources of the server. Performance degradation for memory, CPU or 10 Gbps networking is not noticeable. Performance degradation for disk I/O is at most 30%, a 800% improvement compared to traditional storage virtualisation technologies used by some cloud computing services.

Iodide and Pyodide have brought a standard notebook application to OfficeJS that can be used for business reporting, research and education. They support data science libraries such as NumPy, Pandas, Matplotlib, Plotly, etc. and soon scikit-learn. OfficeJS Iodide notebooks can be used offline or online on any modern HTML5 web browser such as Firefox or Chrome. Thanks to JIO, notebooks can be synchronised with Dropbox, WebDAV, ERP5 and any other storage supported by a JIO plugin. Iodide notebooks can also be embedded through RenderJS into any business application. The dream of ubiquitous data sciences at no infrastructure cost has come to a reality.

European technology suppliers combined with Shenzen ecosystem of small and medium businesses can provide everything that is needed to create latest generation 4G and 5G virtual radio access network (VRAN) infrastructure without depending on USA suppliers and at a fraction of the cost of traditional approaches of the four dominant telecom infrastructure providers.

After making a proof of concept multi-core HTTP server for Python using Lwan and Cython, we decided to extract Lwan's coroutines and evaluate them on their own. This experiment shows that system programming in Cython is possible.

After trying and failing to move to HTTP2 using Apache in 2017, Nexedi has adopted Go language based Caddy server. Initial results of HTTP2 show significant speed improvement and good stability. Next step will be the adoption of QUIC. Migration was smooth and entirely automated thank to a test driver devops approach recently introduced in SlapOS.

The business of industrial automation and control will move away over time from existing, highly profitable, proprietary product lines towards much more flexible yet less profitable open hardware and Free Software. Future profits will eventually emerge from online services based on industrial big data, personalisation, legal regulation and trade secret powered by increasingly smart sensors and gateways at the edge.

A multi-core Python HTTP server that is about 40% to 110% faster than Go can be built by relying on the Cython language and LWAN C library. A proof of concept validates the possibility of high performance system programming in the Cython language.

The existence of cython combined with a clean concurrency model based on technologies such as gevent and pygolang could change the situation if both can be tightly integrated into cython's static cdef code rather than scattered as it is today.

Nexedi has introduced during Zhejiang International Smart Healthcare Innovation Conference the role of Free Big Data to regulate AI market and preserve medical knowledge sharing. Wendelin IA platform was first demoed.

Nexedi is demonstrating during Mobile World Congress 2018 a preview of a Network Management System (NMS) designed for low latency 5G and 4G networks. NMS is published under Free Software license, integrated with Amarisoft 5G / 4G stack and supports Edge Computing for AI offloading.

MariaDB is used at the core of ERP5 and Wendelin. Thanks to NEO distributed object store, MariaDB can store hundred terabyte of big data information such as wind turbine vibration, noise, server logs, etc. We explain in this blog how we currently optimise MariaDB to obtain good results and what remains to be done at the core of MariaDB to reach even further scalability.
